A new method of synthesis of 3,4-difluorobenzonitrile via fluorination step by step from 3,4-dichlorobenzonitrile was posed,which had shown high yield and effective management on cooking,polymerization and darkening when comparing to previous reports.

This new method for synthesizing 3,4-difluorobenzonitrile from 3,4-dichlorobenzonitrile provides high yield and effective management of cooking, polymerization, and darkening compared to previous reports.
